Actually I am pleased with the fourth season being the last of Battlestar Galactica. What makes me pleased about it is that we know, going INTO the season that this is going to be the last. We have the creators and writers PLANNING it to be the last, and so they will do justice to the story line.
Do I wish the story could continue? Of course...but if a season is to be the last, it is best to do it this way...plan it out. It is much easier on the fans, much easier on the cast and crew, and better for the community over all. Maybe sci-fi DID learn a lesson or two from Farscape and SG-1.
(Oh, and BSG going off the air IMPROVES my chances of getting MY show on the air, which is far better than BSG. Just wait and see. Heck, the comic book will be coming out in late July, early August and I'll provide a link to it if anyone is interested).
